- CONFIG_LZMA
-
- If this option is set, support for lzma compressed
- images is included.
-
- Note: The LZMA algorithm adds between 2 and 4KB of code and it
- requires an amount of dynamic memory that is given by the
- formula:
-
- (1846 + 768 << (lc + lp)) * sizeof(uint16)
-
- Where lc and lp stand for, respectively, Literal context bits
- and Literal pos bits.
-
- This value is upper-bounded by 14MB in the worst case. Anyway,
- for a ~4MB large kernel image, we have lc=3 and lp=0 for a
- total amount of (1846 + 768 << (3 + 0)) * 2 = ~41KB... that is
- a very small buffer.
-
- Use the lzmainfo tool to determinate the lc and lp values and
- then calculate the amount of needed dynamic memory (ensuring
- the appropriate CONFIG_SYS_MALLOC_LEN value).
-
CONFIG_LZO
If this option is set, support for LZO compressed images
